Abstract
A weaving loom with a magnetic shuttle comprised of an endless loop for guiding the shuttle to circulate and fly through the shed of warp and a magnetic means constructed as a structure which generates a magnetic force circulating along the endless loop for attracting and driving the shuttle.
Claims4
A weaving loop comprising:
- (a) means for supplying warps in a letoff motion;
- (b) means for forming a shed between said warps;
- (c) a race rail in the form on an endless loop with an elongated opening in the portion which transverses the shed;
- said endless loop of the race rail comprises parallel horizontal portions and two curved portions, each curved portion interconnecting adjacent ends of the horizontal portions,
- (d) a magnetic shuttle movable along said race rail for guiding wefts into the shed;
- (e) magnetic drive means comprising a belt extending along the race rail and electrically operated to circulate around the race rail, and a first series of magnets fixed on said belt for attracting and driving the magnetic shuttle to fly along the race rail;
- (f) a reed assembly comprising a series of aligned reed dents, each reed dent having a horizontal portion so aligned to form a horizontal surface which takes the place of said rail race for guiding said shuttle in passing the shed;
- and
- (g) means connected to said reed assembly for reciprocating it;
- whereby said shuttle is moved at a constant speed in a smooth manner due to said endless race rail.

A weaving loom comprising:
- (a) means for supplying warps in a let-off motion;
- (b) means for forming a shed between the warps in a shedding motion;
- (c) a magnetic shuttle for picking the weft into the shed of the warp transversely in a picking motion;
- (d) a race rail in the form of an endless loop with an elongated opening in the portion which traverses the shed in a picking motion, said loop comprising two parallel horizontal portions and two curved portions, each curved portion interconnecting adjacent ends of the horizontal portions, and each curved portion fitted with a plurality of guiding rollers, whereby the magnetic shuttle passes the curved portion safely;
- (e) magnetic drive means comprising a belt extending along the race rail and electrically operated to circulate around the race rail, and a first series of magnets fixed on said belt for attracting and driving the magnetic shuttle to fly along the race rail;
- (f) a reed assembly for beating the picked weft into the fell in the front line of the warp shed comprising a series of aligned reed dents, each reed dent having a horizontal portion so aligned to form a horizontal surface disposed in the elongated opening of the race rail;
- and
- (g) means connected to said reed assembly for reciprocating it.
